SPECEFICATION forming part of Letters Patent No. 315,747, dated April 14, 1885.

Application filed May 13, 1334. (No rnrdel T 0 all whom it 711/053; concern:

Be it known that I, ALBERT DETWILER, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Gas-Generators; and

I do hereby declare the following to be a full,

I also provided with an aperture into one of its clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked. thereon, which form a part of this specification.

' This invention relates to improvements in gasgenerators.

The object of my invention is to provide an apparatus by which more cheaply, with less attention, simpler manipulation, and greater safety than heretofore air may be saturated with the purified volatile parts of liquid hydrocarbon or converted into purified gas, and supplied to and discharged from suitable orifices for combustion for light-and heat.

My invention is more readily explained by reference to the accompanying drawings, in which Figure 1 is a perspective view of my air-supplying chamber, connected by air-ducts to the gasgenerating chamber. Fig. 2 is a perspective view of the gas-generating chamher with the top removed. Fig. 3 is a vertical section of the gas-generating chamber on a line of 00 x of Fig. 2. Fig. 4. is a vertical section of the airsupplying chamber and the mechanism for operating the diaphragm thereof. Fig. 5 is a sectional view of the liquidsupplying reservoir.

Like letters refer to the same parts in all the views.

The gas-generating chamber A consists of a liquid and gas-tight inclosing-case divided by vertical partitions into a series of compartments, 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10. The air-duct a, leading from the air-supplying chamber, opens into compartment 1 at the top, and the partitions between these compartments are provided with several apertures, o 0, near the bottom, from compartments 1 1102, from 3 to it, from 5 to 6, from '7 to 8, and from the top, from 2 to 3. from 4 to 5, from 6 to 7, and from 8 to 9, and the last of said series of compartments, 10,1's provided with an aperture, q, opening outwardly, having a collar and screw thereon or other equivalent mechanism ,for attaching a tube to conduct the gas to the burner. The gas-generating chamber A is compartments, securely closed, when desired, by cap or other equivalent device, through which naphtha or other gas-producing liquid is supplied to the gas-generating chamber, and said partitions between the several compartments have each one or more apertures, in, at the bottom, adapted to permit the flow of liquid therethrough. from each of said compartments into the next adjoining compartment in the series.

Instead of an aperture closed by a cap through which to supply the liquid directly, I preferably use a reservoir, B, opening by a tube through said aperture into said chamber, which reservoir is provided with an inverted inner reservoir, 2, and valve mechanism, commonvin the student lamps, for controlling and limiting the supply of liquid therefrom, and into which reservoir I introduce a quantity of the liquid-wheretrom the gas-generating chamher is supplied with such amount thereof as is from timeto' time required to keep a supply of the liquid over all the bottom of the gasgenerating chamber. The several compartments of the gas-generator are each filled nearly oiflquite to their tops with cotton waste 1', or other absorbing material, and charcoal s, in alternate .layers, the cotton waste being usedfor and acting as an absorbent of the liquid and the charcoal as a purifier of the liquid and gas. I

The air-supplying chamber consists of the air tight inclosing case D, )rovided with a flexible diaphragm, it, made of leather, rubber, or other flexible material rigidly afitixed to the sides of said case, and dividing the chamber into two compartments, said diaphragm being attached near its center to rod a, said rod a passing out through the inclosing-ease through a striding-box, o, and being movably attached by an arm or other suitable means to the operating mechanism by which sai'd rod and diaphragm are caused to reciprocate. Said air-supplying chamber is provided in each compartment with an aperture having a self-closing inwardly-opening valve, w, for the admission of air, and with an aperture having an outwardly-opening self-closing valve, y, for the discharge of air outwardly into the air-ducts n a, which ducts a n are air-tight, and are rigidly attached to said airsupplying chamber at one extremity at and about said air-discharging apertures, and at the other extremity lead into the gasgenerating chamber through the duct 01 It is obvious that, the diaphragm tin the air-supplying chamber being caused to reciprocate through the mechanism provided for that purpose, air will be taken in through the apertures and open valves at w and discharged outwardly through the apertures and open valves y, and said valves being self-closing, by the return backward pressure of the air, the air will be forced through the ducts n a and a into the gas generating chamber A and through the several compartments thereof and out through the discharge-opening q theref om into the tube leading therefrom to the burner.

That the supply of air to the gas-generating chamber may be constant and steady, I preferably use two or more airsupplying chambers with each gas-generating chamber, so attaching the diaphragm-driving rods to the driving mechanism that the diaphragms will not both or all'reverse their forward or backward movement at the same moment of time.

In passing through the several compartments of said gas-generating chamber, said compartments being supplied with layers of cotton waste and charcoal and with naphtha or other gas-producing liquid, as aforesaid, which liquid is absorbed by the waste and charcoal, over and through which the air passes in its passage through the chamber, the air becomes saturated with the purified volatile gases thereof, rendering it highly inflammable and capa ble of combustion for producing light and heat.

I The charcoal is also a purifier of the liquid and gas, and maybe removed and resupplied from time to time, as required.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. In gas-generators, the generating-chamber A, having a series'of compartments the first of which has an opening from an air-supplying device, and the last of which has an aperture for the discharge of gas, said compartments communicating with each other near the bottom by the small apertures m m, and communicating in pairs one with another by the apertures pp near the top. in combination with a packing of alternate layers of charcoal s s and cotton waste or other absorbing material 1" r, substantially as set forth.

2. In gas-generators, an air-supplying chamber, D, the diaphragm t, rigidly affixed to the sides of said chamber and dividing said chamber into two air-tight compartments, the arm 10, attached to said diaphragm and passing .through the case of the chamber D in a stuffing-boX, o, and adapted to transmitting a reciprocating motion to said diaphragm from the driving mechanism, each compartment of said chamber being provided with an aperture closed by a self closing inwardly opening valve, 10, and an aperture with a self-closing outwardly-opening valve, 3 and the airducts n n therefrom into the gas-generatingchamber, in combination with the gas-generating chamber A, divided into vertical compartments having apertures 0 0 and p p from one compartment to another for the passage of air, and other apertures, m m, for the passage of liquid, and an aperture, q, for discharging the gas, said compartments being packed with alternate layers of cotton waste 1" and charcoal s, and an aperture for supplying said chamber with naphtha, substantially as and for .the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses. Y

ALBERT DETWILER.
